Ambiguous use of Moa/Auk in Unit Test

[renanstig]

Hello,

I'm implementing Unit test in my app, but when I added my ViewController to Tests target, Auk class started giving me the error: "Ambiguous use of auk".

I've already cleaned the derived data and also added both Auk and Moa to Tests target.

I hope you can help me on that, Best regards, Renan.

Hi, thanks again for reporting. I have not seen such a problem before. Are you using CocoaPods?

I have created a demo app with a unit test. It tests loading of remote images into Auk scroll view.

AukSliderInTheMiddle.zip

Xcode: 8.1 (8B62) Cocoapods: 1.2.0.rc.1

The podfile:

platform :ios, '9.0'
use_frameworks!

def shared_pods
  pod 'moa', '~> 8.0'
  pod 'Auk', '~> 7.0'
end

target 'AukSliderInTheMiddle' do
  shared_pods
end

target 'AukSliderInTheMiddleTests' do
  shared_pods
end

View controller:

import UIKit
import Auk

class MyViewController: UIViewController {
  @IBOutlet weak var scrollView: UIScrollView!

  override func viewDidLoad() {
    super.viewDidLoad()
    loadImages();
  }

  func loadImages() {
    scrollView.auk.show(url: "https://bit.ly/auk_image")
    scrollView.auk.show(url: "https://bit.ly/moa_image")
  }
}

The unit test

import XCTest
@testable import AukSliderInTheMiddle
import moa

class AukSliderInTheMiddleTests: XCTestCase {  
  func testExample() {
    // Create simulator to catch downloads of the given image
    let simulator = MoaSimulator.simulate("auk_image")

    // Load view controlle
    let storyboard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
    let vc = storyboard.instantiateViewController(withIdentifier: "myViewController") as! AukSliderInTheMiddle.MyViewController

    // Load view controller
    vc.loadView()

    // Add remote images to the scroll view
    vc.loadImages()

    // Check the image download has been requested
    XCTAssertEqual(1, simulator.downloaders.count)
    XCTAssertEqual("https://bit.ly/auk_image", simulator.downloaders[0].url)

    // Simulate server response with an image
    let image  =  UIImage(named: "35px.png", in: Bundle(for: self.classForCoder), compatibleWith: nil)!
    simulator.respondWithImage(image)

    // Verify the image is loaded into the scroll view
    XCTAssertEqual(35, vc.scrollView.auk.images[0].size.width)
  }
}

Let me know if it helps.

Hello @evgenyneu ,

Thanks for you quick reply. I'm not using CocoaPods, I downloaded the files and imported them to my project. Could this be the problem?

Best regards, Renan.

@renanstig, thanks for the clarification. I have created another demo app where I have included moa and Auk files directly instead of using CocoaPods. The unit tests still work fine for me.

Please note that I am not adding moa and Auk to the test target. Instead the unit test file has

@testable import NameOfYourAppTarget

Here is the demo project: TestingAuk.zip

Let me know if it fixes your problem.
